Kyle Stanley  added the comment:

I just made a rather interesting discovery. Instead of specifically focusing my 
efforts on the logic with interp_destroy(), I decided to take a closer look at 
the failing unit test itself. 

The main test within DestroyTests that's failing is the following:

```
def test_still_running(self):
main, = interpreters.list_all()
interp = interpreters.create()
with _running(interp):
with self.assertRaises(RuntimeError):
interpreters.destroy(interp)
self.assertTrue(interpreters.is_running(interp))
```

(Specifically, "self.assertRaises(RuntimeError): interpreters.destroy(interp)" 
is the main point of failure)

In order to be 100% certain that it was an issue occurring from 
interpreters.destroy(), I decided to add in a bit of a "sanity check" to ensure 
the interpreter was actually running in the first place before destroying it (I 
also added some extra debugging info):

```
def test_still_running(self):
main, = interpreters.list_all()
interp = interpreters.create()
with _running(interp):
self.assertTrue(interpreters.is_running(interp),
msg=f"Interp {interp} should be running before destruction.")

with self.assertRaises(RuntimeError,
msg=f"Should not be able to destroy interp {interp} while"
   " it's still running."):
interpreters.destroy(interp)

self.assertTrue(interpreters.is_running(interp))
```

The results were very interesting...

```

destruction.

--
```

As can be seen from the results above, the interpreter is not even running in 
the first place before it's destroyed, so of course destroy() won't raise an 
RuntimeError. I think this proves that interpreters.destroy() is _not_ where we 
should be focusing our efforts (at least for now). Instead, we should first 
investigate why it's not even running at this point. I suspect the issue 
_might_ be a race condition within the "_running()" context manager that's 
preventing the interpreter from being ran, but I'll have to do some further 
investigation.

I also ran this ~20 times to be 100% certain, and every single one of those 
times the point of failure was at the new assertion check I added before 
destroy(). 

Notably, a rather difficult and hard to explain side effect occurred from 
adding the new assertion. The average number of tests before failure increased 
by a significant amount. In the above test, it was able to pass 306 iterations 
before failing, and in one of my earlier tests it reached over 1000. 

That never happened before on the 3.8 branch, it would very consistently fail 
in the first set of parallel workers if not very soon after. I can say that 
with a degree certainty as well, since I've ran this set of tests a countless 
number of times while trying to debug the failure. But, I have no explanation 
for this.

Do you have any potential ideas, Eric? Also, do you think it might be worth 
adding in the changes I made to DestroyTests.test_still_running above? It 
doesn't directly address the core failure occurring, but I think it improves 
the test significantly; both in functionality and debugging info. I would be 
glad to open a PR if you think the test changes might be useful, as well as 
make any needed adjustments to them.

Look at the source code for the PHP module. Find the parts you need.
My guess is that every hash-related function they call will have a
direct equivalent in Python.

[issue8800] add threading.RWLock

2020-01-14 Thread Éric Larivière


Éric Larivière  added the comment:

Hi,

Sorry to wake up a 10 years old discussion


But I think that you might be interested in the following Python package that I 
created and maintain since few years now:

https://pypi.org/project/readerwriterlock/


1- It implements the three type of reader writer lock:
  - Read Priority
  - Write Priority
  - Fair Priority

2- It matches the interface of python threading.Lock

  More specifically:
def acquire(self, blocking: bool = True, timeout: float = -1) -> bool:
def release(self) -> None:

As you can see it supports the 'blocking' and the 'timeout' parameters) and it 
uses the same methods name

3- It supports context manager (__enter__, __exit__)

4- It is also possible (currently not well documented) to provide a lock 
factory when initializing a new reader writer lock to specify the internal lock 
mechanism to use (by default it uses threading.Lock).

def __init__(self, lock_factory: Callable[[], Lockable] = lambda: 
threading.Lock()) -> None:

This hidden feature allows to offer the possibility to implement your own lock 
mechanism (using port, file on disk, etc, ...) and the reader writer lock will 
internally use it (This open the door for multiprocessing locking)

[issue37224] test__xxsubinterpreters fails randomly



Kyle Stanley  added the comment:

I also just realized that I can run "test.test__xxsubinterpreters.DestroyTests" 
by itself with:

./python -m test test__xxsubinterpreters.DestroyTests -j200 -F -v

For some reason, I hadn't thought of running that class of tests by itself to 
isolate the failure. Prior to this issue, I didn't have experience in debugging 
a group of intermittent failures occurring across different tests. For most 
bugs I've worked on so far, it was a single, clearly defined point of failure; 
or a behavioral issue that wasn't covered in the regression tests.

But, that's certainly useful to know for future debugging and will help to 
improve my workflow for further investigating this issue. It's a lot more 
effective than adding a bunch of skip test annotations throughout the test file!

[issue37224] test__xxsubinterpreters fails randomly



Kyle Stanley  added the comment:

Update: I have a bit of good news and not so great news.

The good news is that I had some time to work on this again, specifically with 
isolating the failure in test__xxsubinterpreters.DestroyTests. Locally, I added 
a few temporary "@unittest.skip()" annotations to the other failing tests in an 
unmodified 3.8 until the only failure that would occur was the following:

==
FAIL: test_still_running (test.test__xxsubinterpreters.DestroyTests)
--
Traceback (most recent call last):
  File "/home/aeros/repos/aeros-cpython/Lib/test/test__xxsubinterpreters.py", 
line 764, in test_still_running
interpreters.destroy(interp)
AssertionError: RuntimeError not raised

--

Once the failure was isolated, I applied my changes on top of that branch with 
the skipped tests to ensure my proposed change resolved the above failure. 
Unfortunately, it still occurred.

It was somewhat disappointing, but I'm certainly glad that I waited to 
thoroughly test the proposed changes before opening a PR. I'll continue working 
on this and see if I can find another fix.

Alright. In that case, I'll do some experimentation when I get the chance and

[issue17005] Add a topological sort algorithm



Tim Peters  added the comment:

Oh, it's fine!  Kahn's algorithm is what I meant when I wrote the "bog-standard 
implementation" before.

I don't believe I've ever seen a context in real life where topsort speed made 
a lick of real difference, so I expect any linear-time (in the sum of the 
number of nodes and edges) would be fine.  Nevertheless, for recording a node's 
successors ("children" in your code), I've always used a list rather than a 
set.  Lists run faster and require less memory than sets, and - unlike sets - 
in Python inherently preserve insertion order.  Iteration order can become 
visible (e.g., if B, C, and D depend on A, what's "the" topsort order?  it 
depends on the order A's children appear when iterating over them - predictable 
with a list, "it depends" with a set).

Note:  "but we have to guard against redundant edges!" would be a red herring.  
Kahn's algorithm couldn't care less, provided that predecessor counts 
accurately reflect the number of edges (redundant or not) entering a node.

[issue17005] Add a topological sort algorithm



Tim Peters  added the comment:

I'll add ts.py, which was a work-in-progress that implements a minor variation 
of most everything I typed about.  If nothing else, its _find_cycle is useful 
as a non-recursive linear-time cycle finder (recursion is deadly here because 
recursive depth-first search can easily "blow the stack" on larger graphs).

There's also "if 1:"/"else:" blocks that set up parallel cases, using threads 
or processes, and two ways of managing the parallelism (the one I showed 
before, and a more elaborate one that puts an upper bound on how large the 
queues can grow - which is sometimes "a problem" for multiprocessing.queue).

[issue17005] Add a topological sort algorithm



Tim Peters  added the comment:

> I am slightly confused about what .prepare() should do. Why
> is this step necessary?

To say "I'm done adding edges".  Any call to add() after prepare() should raise 
an exception.  Likewise, e.g., any call to get_ready() before prepare() should 
raise an exception.  In a bog-standard topsort implementation, saving for each 
node a sequence of successors and a count of predecessors, this is also the 
time to collect all the nodes that have no predecessors (the first batch 
returned by get_ready()).

Much the same could be done without prepare() by get_ready() making a special 
case out of the first time it's called.  That's more magical, though.  "I'm 
done adding edges" is utterly non-magical.

> - Why we need the .done() method here? Why not instead make get_ready()
> simply a generator so you can just write
>
>for node in self.get_ready():

The point of done() is to enable maximum exploitation of parallelism.  As 
already sketched, if a user doesn't care about that, fine, a different method 
(like static_order()) can generate all the nodes in _some_ static topsort 
order, with no need for done().

But suppose a user does care about parallelism.  Consider graph

A -> B
A -> C
A -> D
B -> D

Output A B C D is a topsort, but useless unless the user is content to "do" one 
node at a time.

Instead get_ready() first returns [A] (or a tuple, or a generator, or a set ... 
something iterable).  A is handed out to worker processes/threads, but 
get_ready() will return an empty iterable until done(A) is called.  Indeed, if 
"doing" A fails, it's NOT the case that anything else can ever be started.

If/when "doing A" succeeds, then done(A) is called, and the next get_ready() 
returns [B, C].  Those can be done in parallel, but D can't be started until 
done(B) is called.  done(B) may or may not be called before done(C) is called - 
the topsort itself has no way to know in advance, nor _should_ it impose its 
own view of that.  Note that D does not depend on C, so there's no need to wait 
for _both_ in [B, C] to finish.  It's necessary and sufficient that B be marked 
done() for D to be ready to go.

> It seems that the .done() is very tight to use this API as a "task
> scheduler" but maybe I am doing something here in my understanding
> of the API.

done() says nothing about how the user "should" schedule work items, but 
instead allows get_ready() to return all the work items whose predecessors have 
been marked done() (but haven't already been passed out by get_ready()).  
That's the maximum set of nodes that _can_ be worked on at the time.  The 
topsort class itself has no policy about how or when they "should" be worked 
on, get_ready() is just identifying all the possibilities that exist.  Which is 
impossible to know unless the class is also told which nodes it already passed 
out have finished - the purpose of done().

is_active() eventually returns False when all the nodes passed out by 
get_ready() have been marked done(), _and_ there are no more nodes ready to 
pass out.  At that point, there's a cycle in the input relations if and only if 
there's some node get_ready() never passed out.

In my prototype implementation, that's another thing prepare() does:  checks 
for a cycle, and raises CycleError if there is one.  The user can catch & 
ignore that if they like, and continue calling get_ready() and done() until no 
more progress can be made.  I think it's more likely, though, that the user 
would stare at the cycle attached to the CycleError instance, do whatever it 
takes to break the cycle, and start over again.

I think this API looks very interesting! I have some questions before start 
implementing it to play a bit with it:

- I am slightly confused about what .prepare() should do. Why is this step 
necessary?

- Why we need the .done() method here? Why not instead make get_ready() simply 
a generator so you can just write

for node in self.get_ready():

It seems that the .done() is very tight to use this API as a "task scheduler" 
but maybe I am doing something here in
my understanding of the API.

I had a squiz at the linked-to source code, and it looks like the
corresponding key is stored in a file. Whether that actually
constitutes an improvement in security, I can't say. But to be
compatible, you would have to read the same file.

[issue39295] usage of bitfields in ctypes structures changed between 3.7.5 and 3.7.6

2020-01-14 Thread Matthew Newville



Matthew Newville  added the comment:

@eryksun Sorry for the imprecision -- I was mixing what we do on Linux and 
Windows. A minimum verifiable example for Linux/MacOS would be

import ctypes
class bitstruct(ctypes.Structure):
_fields_ = [('addr', ctypes.c_long),
('rbit', ctypes.c_uint, 1),
('wbit', ctypes.c_uint, 1)]

def handler(args):
print("handler: ", args.addr, args.rbit, args.wbit)

callback = ctypes.CFUNCTYPE(None, bitstruct)(handler)

This works with 3.7.5 but raises a TypeError with 3.7.6.

For Windows (or, well, 64-bit Windows, the only kind we bother to support), we 
find that we have to wrap the function and use a POINTER to the struct, so what 
we really use is more like

import os, functools
def make_callback(args, func):
""" make callback function"""
@functools.wraps(func)
def wrapped(arg, **kwargs):
if hasattr(arg, 'contents'):
return func(arg.contents, **kwargs)
return func(arg, **kwargs)
if os.name =='nt': # also check for 64-bit
cb = ctypes.CFUNCTYPE(None, ctypes.POINTER(args))(wrapped)
else:
cb = ctypes.CFUNCTYPE(None, bitstruct)(handler)
return cb

   callback = make_callback(bitstruct, handler)

The problem here is that code that worked with 3.7.5 raises a TypeError with 
3.7.6.

I don't know that the solution we came up with is actually the best approach.  
I've asked for such guidance a few times now.  I don't know why using a pointer 
would be required for a structure containing a "u_int, 1", but not for other 
structures, but any guidance would be much appreciated.

[issue39338] Data lost randomly from dictionary after creating the dictionary



Tim Peters  added the comment:

What, exactly, in the output shows "the problem"?  When I run it, the `a == b` 
part is always True, while `len(x)` and `len(crazyQuilt2)` are always 30.  The 
other three (len(coordinates), len(x2), len(x3)) are always equal to each 
other, but are monotonically non-increasing across output lines.  For example, 
a typical block of output lines:

(True, 30, 30, 30, 30, 30)
(True, 30, 30, 30, 30, 30)
(True, 30, 30, 30, 30, 30)
(True, 30, 30, 30, 30, 30)
(True, 19, 30, 30, 19, 19)
(True, 19, 30, 30, 19, 19)
(True, 19, 30, 30, 19, 19)
(True, 12, 30, 30, 12, 12)
(True, 12, 30, 30, 12, 12)
(True, 12, 30, 30, 12, 12)

None of that surprises me.  Exactly what about it surprises you?  Or do you get 
different kinds of output (and, if so, exactly what?)?

Here's my guess:  you _intended_ these two lines:

  crazyQuilt2[coordinate2Index] = crazyQuilt2[index]
  crazyQuilt2[index] = crazyQuilt2[coordinate2Index]

to _swap_ the values at indices `index` and `coordinate2Index`.  But they 
don't.  They copy the value originally at `index` into the `coordinate2Index` 
position, and leave the value originally at `index` untouched.

As more copies randomly build up, anything that builds a set or dict out of the 
list naturally gets smaller.

[issue39338] Data lost randomly from dictionary after creating the dictionary

2020-01-14 Thread Zachary Ware



Zachary Ware  added the comment:

I suspect your `useAmp` branch is not doing what you think it's doing: it's 
effectively replacing a random number of entries in your `crazyQuilt2` list 
with a duplicate entry (try `print`ing the list every time around the main loop 
to see what's happening to it).  When you later create a dict using the entries 
of the list as keys there are only so many unique keys, and thus the dict is 
not the same length as the list.

[issue39338] Data lost randomly from dictionary after creating the dictionary

2020-01-14 Thread Y3Kv Bv



New submission from Y3Kv Bv :

Windows 7 x64, Python 3.8.1

I've encountered a very weird issue where after creating a dictionary from a 
list the dictionary ends up being shorter/data is lost from it.
It's absolutely random when it loses, how many and which items are lost.

I've attached the example file with the code that always has a chance to 
trigger the issue for me.

I've managed to figure only this much that when "if useAmp" never triggers, 
data loss will never occur. I've added checkpoints to verify where the loss 
occurs and it's not caused by "if useAmp" block directly, data loss happens 
exactly after the dictionary is created.

[issue39336] Immutable module type can't be used as package in custom loader

2020-01-14 Thread Brett Cannon



Brett Cannon  added the comment:

So I think this is way too marginal a use-case to expand the API to let loaders 
inject themselves into the semantics of it.

I assume going with option 1 but raising an ImportWarning would be too noisy 
for your use-case? If not I'm totally fine with that solution.

[issue39337] codecs.lookup() ignores non-ASCII characters, whereas encodings.normalize_encoding() copies them


New submission from STINNER Victor :

bpo-37751 changed codecs.lookup() in a subtle way: non-ASCII characters are now 
ignored, whereas they were copied unmodified previously.

I would prefer that codecs.lookup() and encodings.normalize_encoding() behave 
the same. Either always ignore or always copy.

Moreover, it seems like there is no test on how the encoding names are 
normalized in codecs.register(). I recall that using codecs.register() in an 
unit test causes troubles since there is no API to unregister a search 
function. Maybe we should just add a private function for test in _testcapi.

Serhiy Storchaka wrote an example on my PR:
https://github.com/python/cpython/pull/17997/files

> There are other differences. For example, normalize_encoding("КОИ-8") returns 
> "кои_8", but codecs.lookup normalizes it to "8".

[issue39336] Immutable module type can't be used as package in custom loader



New submission from Dino Viehland :

I'm trying to create a custom module type for a custom loader where the 
returned modules are immutable.  But I'm running into an issue where the 
immutable module type can't be used as a module for a package.  That's because 
the import machinery calls setattr to set the module as an attribute on it's 
parent in _boostrap.py

# Set the module as an attribute on its parent.
parent_module = sys.modules[parent]
setattr(parent_module, name.rpartition('.')[2], module)

I'd be okay if for these immutable module types they simply didn't have their 
children packages published on them.

A simple simulation of this is a package which replaces its self with an object 
which doesn't support adding arbitrary attributes:

x/__init__.py:
import sys

class MyMod(object):
__slots__ = ['__builtins__', '__cached__', '__doc__', '__file__', 
'__loader__', '__name__', '__package__', '__path__', '__spec__']
def __init__(self):
for attr in self.__slots__:
setattr(self, attr, globals()[attr])


sys.modules['x'] = MyMod()

x/y.py:
# Empty file

>>> from x import y
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 983, in _find_and_load
  File "", line 971, in _find_and_load_unlocked
AttributeError: 'MyMod' object has no attribute 'y'

There's a few different options I could see on how this could be supported:
1) Simply handle the attribute error and allow things to continue
2) Add ability for the modules loader to perform the set, and fallback to 
setattr if one isn't available.  Such as:
 getattr(parent_module, 'add_child_module', setattr)(parent_module, 
name.rpartition('.')[2], module)
3) Add the ability for the module type to handle the setattr:
 getattr(type(parent_module), 'add_child_module', 
fallback)(parent_module, 
, name.rpartition('.')[2], module)

New submission from Hrvoje Abraham :

>>> from decimal import Decimal

I would expect -123.0, even considering Py2 rounding convention details (away 
from zero), Decimal rounding convention (default rounding=ROUND_HALF_EVEN), 
floating point specifics...

Works as expected in Py3. Both Py2 and Py3 use same default Decimal 
rounding=ROUND_HALF_EVEN.

Could be I'm missing some detail...

[issue39295] usage of bitfields in ctypes structures changed between 3.7.5 and 3.7.6

2020-01-14 Thread Eryk Sun



Eryk Sun  added the comment:

> With Python 3.7.6 this raises an exception at the ctypes.CFUNCTYPE() 
> call with
> ...
> TypeError: item 1 in _argtypes_ passes a struct/union with a bitfield

I cannot reproduce the problem as stated in 3.7.6 in Windows. The TypeError 
only occurs if I use the struct type directly in argtypes, not a pointer to the 
struct type. For example:

>>> class A(ctypes.Structure):
... _fields_ = (('x', ctypes.c_uint, 1),)

>>> class P_A(ctypes._Pointer):
... _type_ = A
...

allowed:

>>> class FP_P_A(ctypes._CFuncPtr):
... _flags_ = ctypes._FUNCFLAG_CDECL
... _argtypes_ = (P_A,)

disallowed:

>>> class FP_A(ctypes._CFuncPtr):
... _flags_ = ctypes._FUNCFLAG_CDECL
... _argtypes_ = (A,)
...
Traceback (most recent call last):
  File "", line 1, in 
TypeError: item 1 in _argtypes_ passes a struct/union with a bitfield by 
value, which is unsupported.

This seems rights to me. There is no problem passing a pointer as a function 
parameter.

[issue39333] argparse should offer an alternative to SystemExit in case a parse fails

2020-01-14 Thread Jack Orenstein



New submission from Jack Orenstein :

If parse_args fails, SystemExit is raised, carrying an exit code of 2, and the 
help message is printed. For an embedded usage of argparse, this behavior is 
undesirable.

I am writing an interactive console application, using argparse to parse input. 
When a parse fails, I would like to print an error message and continue, not 
terminate the program. Currently, I need to catch SystemExit to be able to do 
this, which has obvious problems, (e.g., what if something other that argparse 
is causing the exit?)

I'd like to see some way to specify alternative behavior, e.g. raise an 
exception of a given type.

[issue39296] Windows register keys

Tony  added the comment:

Hi Steve,

Thank you for this. 
I know about the working of WOW64 and the redirection to the 
(HKEY_LOCAL_MACHINE) ..\Wow6432Node, that is explained on md.docs.
The HKEY_CURRENT_USER redirection is not well explained, and so it appears I’m 
not the only one (Google) who was confused about this behavior.
So, again, many thanks for your explanation!

Tony Kalf.

Onderwerp: [issue39296] Windows register keys

Steve Dower  added the comment:

You should read the version number from the Version or SysVersion values, 
rather than from the tag.

Having -32 in the key name is a compatibility requirement. Without it, if you 
installed 32-bit and 64-bit versions for the current user (which is now the 
default), they would overwrite each other.

The Wow6432Node key is due to Windows, not Python. We don't decide the name or 
when it is used, and Windows determined that HKEY_CURRENT_USER is not subject 
to registry redirection. That's why you don't see it there.

Hope that helps clarify what's going on.

Re: How to compare in python an input value with an hashed value in mysql table?

2020-01-14 Thread Growth Hacking Formation

Thanks for your help.

Litle details,

the license key is goldQ3T8-1QRD-5QBI-9F22

and it is stored in database already encrypted.
License key is not saved in database with clear text. It is already encrypted.
I am not sure what is this hash column for?

License key =>
def50200962018b6bbed50fc53abca6bb076eb2947fc379e69bd38dcea9f8fbe29eedd43f1148e721d5f6657d8d0152356f5a7ba566dde545a9a354c7b42af88fe4ea7775a4e2ee1a26d8b8f7e3272cf5a8bbe38197fdf19e1726d5e2d769bae408cd511706388abad5a75

hash =>
25138e045e9f50022331340a26d0eecbd0d7ca6bfefee0275749025c4f56c3a8
see screenshot:
http://prntscr.com/qnhz8h

I thought the "hash" column was the key to encrypt or decrypt the license
stored in column "license_key".

So I run your code for testing with appropriate licese key:
Python Code:
1
2
3
4
5
6 from hashlib import md5, sha256, sha512
key = 'goldQ3T8-1QRD-5QBI-9F22'
for hash_func in (md5, sha256, sha512):
print(hash_func(key.encode()).hexdigest())
and it give this outpu:
Output:
ecc58b55c33fe6dfe3b49d6d63aad65b

Process finished with exit code 0
As you can see, here the code doesn't give same result than database.

Regarding wordpress login, I didn't find any python library which can can
handle this authentification process.

I contacted the developper, and he replied me this message:

Hello @formationgrowthhacking,
thank you for your message and for using my plugin.
For license key hashing, I implemented the PHP native method hash_hmac(), using
the sha256 algorithm.
You can check out the class which is responsible for encryption, decryption,
and hashing here:
https://plugins.trac.wordpress.org/browser/license-manager-for-woocommerce/trunk/includes/Crypto.php
Let me know if this helped!

But he may not know python. I need help of python expert.

Does this update help for better understanding my issue?

[issue39312] Expose placeholder reparse points in Windows

2020-01-14 Thread Eryk Sun



Eryk Sun  added the comment:

Okay, a well-known third-party library will work if a script/application really 
needs this information. I just wanted to bring it up for consideration because 
I saw an issue for cross-platform PowerShell 6 [1] where it was decided to 
disable placeholder disguising, but that particular decision was motivated by 
the need to remain compatible with Windows PowerShell 5.

[1] https://github.com/PowerShell/PowerShell/pull/8745

> Recalling our debates about symlinks, I'd have to say that nothing 
> about placeholder files qualifies them as links, regardless of 
> whether Powershell puts "l" in the attributes summary :)

Certainly. A link (broadly speaking, including Unix-style symlinks and mount 
points) has to be a name surrogate. These OneDrive reparse points do not have 
the [N]ame surrogate bit set. It's not even allowed to be set because they have 
the [D]irectory bit set, which allows the directory entry in the filesystem to 
contain files. This is explained in km\ntifs.h:


// The reparse tags are a ULONG. The 32 bits are laid out as follows:
//
//   3 3 2 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1
//   1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0
//  +-+-+-+-+---+---+
//  |M|R|N|D| Reserved bits |   Reparse Tag Value   |
//  +-+-+-+-+---+---+
//
// M is the Microsoft bit. When set to 1, it denotes a tag owned by 
Microsoft.
//   All ISVs must use a tag with a 0 in this position.
//   Note: If a Microsoft tag is used by non-Microsoft software, the
//   behavior is not defined.
//
// R is reserved.  Must be zero for non-Microsoft tags.
//
// N is name surrogate. When set to 1, the file represents another named
//   entity in the system.
//
// D is the directory bit. When set to 1, indicates that any directory
//   with this reparse tag can have children. Has no special meaning when 
used
//   on a non-directory file. Not compatible with the name surrogate bit.

Contact the person responsible for the data in your database.
Ask him which hashing algorithm should be used to verify the
license info provided by a user against the database info.

Note: there are many different hashing functions (e.g. "md5", "sha1",
"sha256", ...) and often their use involves an additionl secret
(besides the hashed data). Best get those details from a
knowledgable person than from us.

[issue39312] Expose placeholder reparse points in Windows

2020-01-14 Thread Steve Dower



Steve Dower  added the comment:

Given the minimum version requirement, I'd rather this support go into a 
third-party library. (Seems like a great candidate for a context manager, too.)

Recalling our debates about symlinks, I'd have to say that nothing about 
placeholder files qualifies them as links, regardless of whether Powershell 
puts "l" in the attributes summary :)

The ecosystem could really do with a Windows-aware filesystem library for this 
kind of support (and I might already be working on one occasionally, pitching 
it as a MSFT-supported package, which is why it's not public yet).

I'd rather keep the standard library as lowest common denominator for system 
interactions, particularly for behaviour like this that is either 
automatic+surprising or manual+platform-specific and insufficiently compelling 
(os.add_dll_directory being an example of something that was sufficiently 
compelling).

So I'm going to mark this as rejected, and steal the idea for my own library :D

[issue39318] NamedTemporaryFile could cause double-close on an fd if _TemporaryFileWrapper throws

2020-01-14 Thread Eryk Sun



Eryk Sun  added the comment:

> I afraid that removing a file while the file descriptor is open 
> may not work on Windows. Seems this case is not well tested.

os.remove will succeed on a file that's opened with O_TEMPORARY, which shares 
delete access (i.e. FILE_SHARE_DELETE).

With classic Windows delete semantics, deleting a file sets the delete 
disposition on the filesystem's underlying file/link control block (FCB/LCB). 
The filesystem doesn't unlink the file from the directory until all File object 
references have been finalized. (A File handle refers to a kernel File object, 
which refers to an FCB/LCB in a filesystem. An FCB/LCB can be referenced by 
multiple File objects, such as from multiple CreateFileW calls, and a File 
object can be referenced by multiple handles, such as via inheritance or 
DuplicateHandle.) The deleted file remains accessible to existing File objects, 
and a File object with delete access can even be used to clear the delete 
disposition (i.e. undelete the file) via SetFileInformationByHandle: 
FileDispositionInfo. The file remains linked and visible in the parent 
directory, but no new access is allowed while its delete disposition is set. 
The parent directory cannot itself be deleted until the file is unlinked.

In Windows 10 1903, DeleteFileW has also been updated to use POSIX semantics if 
the filesystem supports it, which includes NTFS on the system drive, where temp 
files are usually created. With POSIX semantics, the file is unlinked as soon 
as DeleteFileW closes its File handle. All existing File objects can continue 
to access the file even though it's no longer linked in the directory. This 
includes being able to call GetFinalPathNameByHandleW, which, at least for 
NTFS, will show that the file has been moved to the special system directory 
"\$Extend\$Deleted" and renamed according to its file ID. As is usual for a 
deleted file, no new access is allowed, i.e. we cannot reopen a file in the 
"$Deleted" directory. Another change with POSIX semantics is that the delete is 
final. Existing File objects that have delete access are not allowed to clear 
the delete disposition (i.e. undelete the file).

[issue39330] Way to build without IDLE

2020-01-14 Thread Zachary Ware



Zachary Ware  added the comment:

I'm not sure what you mean here.  IDLE is a pure-Python application, though it 
does depend on the optional tkinter package.  If you're on a UNIX platform and 
Tcl/Tk headers and libraries can't be found, _tkinter won't be built and you 
won't be able to run IDLE; on Windows if you pass the --no-tkinter (or -E) flag 
to PCbuild/build.bat, _tkinter won't be built and you won't be able to run 
IDLE.  In neither case is it an error to not have _tkinter (unless you try to 
import it).

There is no "building" of IDLE itself, and thus no way to not build it :)

[issue39331] 2to3 mishandles indented imports

2020-01-14 Thread Guy Galun



New submission from Guy Galun :

When encountering an import that should be removed in Python 3 (e.g. "from 
itertools import izip"), 2to3 changes it a blank line, which may cause a 
runtime error if that import was indented:

error: module importing failed: expected an indented block (ptypes.py, line 10)
  File "temp.py", line 1, in 
  File "./lldbmacros/xnu.py", line 771, in 
from memory import *
  File "./lldbmacros/memory.py", line 11, in 
import macho
  File "./lldbmacros/macho.py", line 3, in 
from macholib import MachO as macho
  File "./lldbmacros/macholib/MachO.py", line 10, in 
from .mach_o import MH_FILETYPE_SHORTNAMES, LC_DYSYMTAB, LC_SYMTAB
  File "./lldbmacros/macholib/mach_o.py", line 16, in 
from macholib.ptypes import p_uint32, p_uint64, Structure, p_long, 
pypackable

Relevant section before 2to3:

try:
from itertools import izip, imap
except ImportError:
izip, imap = zip, map
from itertools import chain, starmap

And after 2to3:

try:

except ImportError:
izip, imap = zip, map
from itertools import chain, starmap


* Side note:
This specific case may only be problematic with scripts that are partially 
aware of Python 3, otherwise they wouldn't try-catch that import.

* Proposed solution:
In case of that kind of import being the single line of an indented block, 
change it to "pass" instead of a blank line.

Can you be specific about which modules you are trying to install?  I
don't see any sign of a python package called 'webbrowsing' anywhere
on the internet, for instance.  Are you possibly looking for the
'webbrowser' module?  If so, it's not installed via pip, it's part of
the python standard library (see docs here:
https://docs.python.org/3/library/webbrowser.html).  There's also an
'os' module in the standard library
(https://docs.python.org/3/library/os.html). Are those the modules you

see: https://github.com/python/cpython/pull/17958#issuecomment-573390867

I've noticed that LMTP does not support the timeout parameter.
See: https://docs.python.org/3.9/library/smtplib.html#smtplib.LMTP

However, LMTP also able to use the socket which is created from SMTP.
IMHO LMTP needs to support the timeout parameter.

latexcodec uses encoding names like "latex+ascii" and their search function 
used "+" as a separator.

Don't worry, I just fixed latexcodec, my fix is already merged upstream! I 
simply changed the search function to split on "_" if the name contains "_".

[issue37751] In codecs, function 'normalizestring' should convert both spaces and hyphens to underscores.

2020-01-14 Thread Marc-Andre Lemburg



Marc-Andre Lemburg  added the comment:

Just to clarify: the change in the C implementation was the breaking change. 
The patch just restores the previous behavior: 
https://github.com/python/cpython/blob/master/Lib/encodings/__init__.py#L43

Please note that external codec packages should not rely on the semantics of 
the Python stdlib encodings package's search function. They should really 
register their own search function: 
https://docs.python.org/3.9/library/codecs.html#codecs.register

It's good practice to always only use ASCII lower case chars and the underscore 
for codec names.

I reopen the issue. I proposed PR 17997 to *document* the incompatible change 
in What's New in Python 3.8. IMO it's a deliberate change and it's correct.

I rely on Marc-Andre Lemburg who implemented codecs and encodings modules. He 
wrote: "Jordon is right. Conversion has to be to underscores, not hyphens.".

Slightly off-topic:

Why would you store *both* an encrypted key and a hash?
If you have the encrypted key in the database and the encryption key on your 
site (presumably in the Python code) and your site is hacked, all the license 
keys are potentially in the open.
And if your key is on the site you can as well encrypt the entered license key 
and compare it to the stored encrypted key.

This supposes Python 3:

Let's assume the entered key is in ASCII and stored in the variable 'key'.

from hashlib import sha256
key = bytes(key, 'ascii')
hash = sha256(key).hexdigest()

Now you can compare hash with the stored hash in the database. Of course this 
only works if that stored hash has been calculated in the same way from the 
same key.

On Python 2 (which you shouldn't use) you can leave out the "key = bytes(key, 
'ascii')" part.

You can of course make it more sophisticated, for example by using a salt. 
Unless your keys are extremely valuable, I wouldn't bother with that.
